[Boost-users] boost::range vs && (rvalue ref)

Passing range by ref (&) is fine, but using (&&) results in and error. Any ideas? #include #include <vector> template<typename out_t> void F (out_t && o) { typedef typename boost::range_value::type T; } void G() { std::vector<int> v; F (v); } usr/local/src/boost_1_52_0/boost/mpl/eval_if.hpp:60:31: error: no type named ‘type’ in ‘boost::mpl::eval_if_c, boost::range_mutable_iterator >::f_ {aka struct boost::range_mutable_iterator}’ bug.cc: In instantiation of ‘void F(out_t&&) [with out_t = std::vector<int>&]’: bug.cc:12:7: required from here bug.cc:6:52: error: no type named ‘type’ in ‘struct boost::range_value’
